hschlueter d97de5b9f0 Use microseconds not nanoseconds for GlFrameProcessor.
This requires an additional nanos to micros conversion because
the SurfaceTexture uses nanos. But as the timestamps from the
MediaCodec decoder (propagated in DefaultCodec#releaseOutputBuffer) are
in microseconds no precision is lost here.

Also add test that checks output video duration.
